Description

縫紉機的進給機構Feed mechanism of sewing machine

本發明涉及一種縫紉機的進給機構，尤指一種對左、右兩片布料進行縫合時，較適合將布料朝向布料進給方向搬送的出臂型縫紉機的進給機構。The invention relates to a feeding mechanism of a sewing machine, in particular to a feeding mechanism of an arm-out type sewing machine which is more suitable for conveying the cloth toward the feeding direction when sewing left and right pieces of cloth.

現有的出臂型縫紉機的進給機構，其於縫紉機下部且沿著水平方向上延伸之機體的長度方向將進給齒連動桿(進給台)配置於機體內部，而沿機體的延伸方向搬送布料。該出臂型縫紉機的進給機構的進給齒連動桿，是由前進給齒連動桿(主進給台)及後進給齒連動桿(差動進給台)構成，且該些前、後的進給齒連動桿係於機體內左、右並排設置。前進給齒連動桿及後進給齒連動桿的前端分別安裝有前進給齒(主進給齒)及後進給齒(差動進給齒)。In the feed mechanism of the existing arm-out sewing machine, the feed tooth linkage rod (feed table) is arranged inside the body at the bottom of the sewing machine and along the length direction of the body extending in the horizontal direction, and is conveyed along the extending direction of the body. fabric. The feed tooth link of the feed mechanism of the arm-out type sewing machine is composed of a forward feed tooth link (main feed table) and a rear feed tooth link (differential feed table), and the front and rear The feed tooth linkage rod is arranged side by side on the left and right in the machine body. The forward feed teeth (main feed teeth) and the rear feed teeth (differential feed teeth) are respectively installed on the front ends of the forward feed gear linkage rod and the rear feed teeth linkage rod.

然而現有的出臂型縫紉機，所縫合的左、右兩片布料係於進給齒上左、右排列而被朝布料進給方向搬送，若所縫合的左、右兩片布料的厚度或原料不同，則左、右的布料的進給量會有不同，若對曲線部位進行縫製，則於左、右的布料需要有不同的進給量，因此現有的出臂型縫紉機存在有縫製品上產生起皺等問題。However, in the existing arm-out type sewing machines, the left and right pieces of fabric to be stitched are arranged left and right on the feed teeth and are conveyed toward the feeding direction of the fabric. If it is different, the feeding amount of the left and right fabrics will be different. If the curved parts are sewn, the left and right fabrics need to have different feeding amounts. Therefore, the existing arm-out type sewing machines have problems Problems such as wrinkling occur.

另有一種現有的出臂型縫紉機的進給機構，進給機構係藉由與主軸連動且沿布料進給方向的垂直面內進行橢圓運動的主進給齒、第一差動進給齒及第二差動進給齒，將載置於機體上的布料朝向布料進給方向搬送。進給機構具備對主軸的每一轉中第一差動進給齒於前、後方向的移動量進行調節的第一差動進給量調節機構。進給機構具備對主軸的每一轉中第二差動進給齒於前後方向的移動量進行調節的第二差動進給量調節機構。是以，於所縫合的左、右兩片布料的厚度或原料不同時、或對曲線部位進行縫製時，仍能適當的搬送左、右兩片的布料。然而，該縫紉機的進給機構，其第一、第二差動進給量調節機構的調節件位於縫紉機殼體相對的兩側，因此調整操作較不方便，且難以檢視調整有無同步，製作成本也較高。There is also a feed mechanism of an existing arm-out type sewing machine. The feed mechanism consists of the main feed teeth, the first differential feed teeth and the The second differential feed teeth convey the cloth placed on the machine body toward the cloth feeding direction. The feed mechanism has a first differential feed adjustment mechanism for adjusting the movement amount of the first differential feed teeth in the front and rear directions in each revolution of the main shaft. The feed mechanism includes a second differential feed adjustment mechanism that adjusts the amount of movement of the second differential feed teeth in the front-rear direction for each revolution of the main shaft. Therefore, when the thickness or material of the left and right pieces of fabric to be sewn is different, or when the curved part is sewn, the left and right pieces of fabric can still be properly conveyed. However, in the feeding mechanism of the sewing machine, the adjusting members of the first and second differential feed adjustment mechanisms are located on opposite sides of the sewing machine housing, so the adjustment operation is inconvenient, and it is difficult to check whether the adjustment is synchronized, and the production cost is low. Also higher.
